warning D9002、fatal error C1083: Cannot open include file: ‘basetsd.h‘ 、cannot run ‘rc.exe‘问题摸索解决

亲测有效，最终成功解决了环境问题，并且根据官网模型成功做了预测 我的配置是Win10+YOLOX+Torch1.9+CUDA11.4

这是我在装YOLOX的环境：yolox和 pycocotools 编译时出的问题，具体解决过程如下：

在windows上安装好pytorch环境后，跑YOLOX出现了一些问题，主要是yolox的编译问题和pycocotools的编译不成功问题，摸索了一下，暂时记录一下过程。如果有好的解决方法，也在此请读者予以告知，不甚感激。

百度搜索后有说是win10 SDK的问题，于是我安装了Windows 10 SDK，重新编译pycocotools，发现错误变了
我原想过能不能直接下载缺少的文件，直接放在缺失位置，看看是什么情况，是否可以解决
根据搜索的解决方法，我先安装了Windows 10 SDK，编译问题如下：

看来对我的没有作用，又踩了个坑
根据最新的报错，我又找了篇博客看看，建议是从C:\Program Files (x86)\Windows Kits\8.1\bin\x86 拷贝rc.exe 和 rcdll.dll到如下位置
我的是C:\Program Files (x86)\Windows Kits\10\bin\x86 ，但是在目录下并没有找到这两个文件，我于是搜索一下找到了，对应x86,拷贝出来，直接放进去了，再次编译pycocotools，结果如下：

出现了警告，说GCC会不兼容，但整体都没有报错编译结束了，貌似yolox也编译好了，接下来就可以试试行不行了。总之这次尝试算是把两个库给编译好了，至于其他问题再一步步解决吧。

后面仍旧出了一点小插曲：

During handling of the above exception, another exception occurred:

但是，所幸是解决了，我的成功预测结果如下：
